The higher cost of work undertaken by registered social landlords is the basis for the calculation. Social landlords business plans are based on 30 years which will help inform the investment decisions they make. The figures used in the calculation were based on actual investment by registered social landlords. When we did the calculation we took into account the anticipated reduction in local authority homes, including where a transfer ballot was pending or where a transfer scheme was included on the transfer programme. The calculation is the additional resources needed on top of what local authorities are already spending on the delivery of decent homes, this will include not only money from Government but also money from their own resources. .Where local authorities are able to find additional resources from their own budgets they often do so, which has helped many councils meet their decent homes target. However, many councils have made it clear that they cannot find additional resources from within their existing budgets.
